Step-by-Step Guide
- Talk to your family doctor
Ask your family doctor or paediatrician about an autism assessment referral and the current expected wait for your area. Keep the referral date and any written timeline.
- Consider a private psychologist
No referral is needed for a private psychological assessment. Fees vary by provider, so ask for a written quote before you book. Some insurance plans partially cover this.
- Prepare for the assessment
Gather developmental history notes, school reports, teacher observations, and any previous assessments. This documentation speeds up the process.
- Receive your written report
The report must use DSM-5 diagnostic criteria and be authored by a registered psychologist, psychiatrist, or developmental pediatrician. Confirm this before the assessment.
- Use the diagnosis to register for OAP
Once you have the written report, you can register your child for the Ontario Autism Program. Registration is the first step toward accessing funded services.
